Premium product!
Must have, save hundreds over time. Rinse and put back on. Get the cleaners and spray to keep it new.

2024 Honda CR-V
Worked for 2024 Honda CR-V Sport (Hybrid). Sizing was appropriate and the new filter slid in without any issue. Consider the filter to be of good quality. Would recommend.
